Mississauga Digital Orthoimagery, 2000

Coordinate system: 26917

Abstract:

This City of Mississauga aerial photography covers the area of Mississauga. These photos are in black and white, and were taken in April of 2000 by the Northway-Photomap Inc at a scale of 1:4,000 and 1:8,000.

The first aerial surveys of Mississauga were undertaken in 1944. Since then, the city has produced aerial photography every five to ten years until 2002, when it became annual.

This data set contains the lower-resolution JPG version of the imagery for view, and a high-resolution ECW version for direct download. It is recommended to use the low-res image considering the size of the high-res version.

The original format of the raster image are .ecw and .ers.

The digitized Aerial Imagery was originally stored by the City of Mississauga in ERMapper ECW format. In most cases, a single orthometric file covers the entire city area. All maps use rectangular coordinate values expressed in metres and based on the 6 degree Universal Transverse Mercator system, NAD 1983. Aerial imagery for Mississauga is available from 1944 to present. Original images from 1986 to 2003 used the North American 1927 (NAD27) datum. No datum information is known for images prior to 1986. Images prior to 1986 were projected to the NAD83 datum by the City of Mississauga.
